The index shows which Internet Service Providers (ISPs) provide the best Netflix streaming experience during primetime.

Netflix says the average speed on Comcast for Netflix streams jumped 65 percent from 1.51Mbps in January to 2.5Mbps in March.

The increase is a direct result of a deal in February where Netflix is paying Comcast to use their content-delivery network (CDN) rather than using third parties and Open Connect, Netflix’s CDN initiative.
